Pneumatic Weigh Filling System

This pneumatic gain-in-weight filling system conveys and weighs free-flowing bulk solids, and discharges the material into bulk bags dust-free. The filter receiver of a Pneumati-Con vacuum dilute-phase pneumatic conveying system is mounted on load cells, enabling the controller to stop the flow of material once an accurate batch weight has been accumulated. A "fill" button on the Twin-Centerpost bulk bag filler actuates a blower to remove bag creases, and then opens a slide gate valve to discharge the batch into the bag at high rates, as a vibratory deck densifies the material to stabilize the bag. The filler is mounted on a secondary set of load cells to check-weigh the filled bag. A port within the discharge spout vents displaced air and dust to a remote bag house. The controller then releases the bag straps and deflates the spout seal, allowing the operator to tie-off the spout and remove the filled bag.
